Abstract
Self-assembly of peptides is a powerful method of preparing nanostructured materials. Peptides frequently utilize charged groups as a convenient switch for controlling assembly state by pH, ionic strength or temperature. In this study, the molecular properties and gel-forming ability of Chlamys farreri protein hydrolysates were studied. According to self-assembled theory, the presence of isoleucine at position 'a' and leucine at 'd' causes a switch between coiled-coil structures. Compared to P-2-CG, the components of α-helix (23.60 ± 0.56%) were changed into β-sheet (4.83 ± 2.86%) in the secondary structure of the hydrogel induced by ZnCl2. NMR siginals appeared at high field,which indicated hydrogen bonds were formed between P-2-CG and solvent environments at 20 °C. With temperature going up, the hydrogen bonds were broken and nanofibrils were changed into dense aggregates. We expected that P-2-CG could provide a new candidate for preparing metal-induced nanofibers or hydrogels with further applications in food industry.

Optimisation and Characterisation of the Protein Hydrolysate of Scallops ( Argopecten purpuratus) Visceral By-Products. Foods 2023; 12:foods12102003. [PMID: 37238820 DOI: 10.3390/foods12102003] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 04/25/2023] [Accepted: 04/29/2023] [Indexed: 05/28/2023] Open
Abstract
In this research, scallops (Argopecten purpuratus) visceral meal (SVM) and defatted meal (SVMD) were analysed for their proximal composition, protein solubility, and amino acid profile. Hydrolysed proteins isolated from the scallop's viscera (SPH) were optimised and characterised using response surface methodology with a Box-Behnken design. The effects of three independent variables were examined: temperature (30-70 °C), time (40-80 min), and enzyme concentration (0.1-0.5 AU/g protein) on the degree of hydrolysis (DH %) as a response variable. The optimised protein hydrolysates were analysed for their proximal composition, yield, DH %, protein solubility, amino acid composition, and molecular profile. This research showed that defatted and isolation protein stages are not necessaries to obtain the hydrolysate protein. The conditions of the optimization process were 57 °C, 62 min and 0.38 AU/g protein. The amino acid composition showed a balanced profile since it conforms to the Food and Agriculture Organisation/World Health Organisation recommendations for healthy nutrition. The predominant amino acids were aspartic acid + asparagine, glutamic acid + Glutamate, Glycine, and Arginine. The protein hydrolysates' yield and DH % were higher than 90% and close to 20%, respectively, with molecular weight between 1-5 kDa. The results indicate that the protein hydrolysates of scallops (Argopecten purpuratus) visceral by product optimised and characterised was suitable a lab-scale. Further research is necessary to study the bioactivity properties with biologic activity of these hydrolysates.

Abstract
Food proteins are important nutrients for human health and thus make significant contributions to the unique functions of different foods. The modification of proteins through physical and biological processing could improve the functional and nutritional properties of food products; these changes can be attributed to modifications in particle size, solubility, emulsion stability, secondary structure, as well as the bioactivities of the proteins. Physical processing treatments might promote physical phenomena, such as combined friction, collision, shear forces, turbulence, and cavitation of particles, and lead to changes in the particle sizes of proteins. The objective of this review is to illustrate the effect of physical and biological processing on the structure, and physical and chemical properties of food-derived proteins and provide insights into the mechanism underlying structural changes. Many studies have suggested that physical and biological processes, such as ultrasound treatment, high pressure homogenization, ball mill treatment, and enzymatic hydrolysis could affect the structure, physical properties, and chemical properties of food-derived proteins. Some important applications of food-derived proteins are also discussed based on the relationships between their physical, chemical, and functional properties. Perspectives from fundamental or practical research are also brought in to provide a complete picture of the currently available relevant data.
